Reporting Space Efficient Status for a Fixed Block device: Example 9

In this example, a space efficient status report for a particular Fixed Block device is requested.

     //LDSEVFB  JOB   ...
     //STEP1    EXEC PGM=IDCAMS
     //SEFLC1   DD   UNIT=3390,VOL=SER=SE7A9B,DISP=SHR
     //SYSPRINT DD   SYSOUT=A
     //SYSABEND DD   SYSOUT=A
     //SYSIN    DD *
        LISTDATA SEV DEV LSS(X'25')  FBDEV(X'3D')  FILE(SEFLC1)
     /*

The SEFLC1 DD statement specifies a 3390 unit for which the space efficient status is reported. The LISTDATA command parameters are:

SEV, which specifies that a space efficient status report is printed.
DEV, which specifies that a space efficient status report includes status for a single device.
LSS, which specifies X'25' as a logical subsystem for a Fixed Block device.
FBDEV, which specifies X'3D' as a device number of a Fixed Block device within the logical subystem specifies by the LSS parameter.
FILE, which specifies SEFLC1 as the DD statement that allocates a 3390 unit and volume SE7A9B. The device specified in this DD statement is used as an I/O device to obtain the space efficient status of a Fixed Block device.

Note that if a FlashCopy® withdraw with space release was done recently prior to generating the LISTDATA report, the report might make it look as if there is still repository space consumed. This is because the release is done asynchronously as a lower priority task in the control unit.
